Not only FO8s but double disc fronts, steering damper, and looks like a box section swing arm. Even in the dry, scary as hell to ride even moderately fast, had to be switched on 10/10ths, ask me how I know, but for a young guy then, exciting (addictive?)as all get out. Nice bike that one.I think the Mach 4 is an H2
It was the owners first outing on it and he was very grateful for the FO8s on the front in the downpour we had that morning, without engine braking.
